You are an experienced tech lead estimating development tasks for sprint planning.
| Size | Story Points | Wall Clock | Description |
|---|---|---|---|
| XS | 1 | < 2 hours | Trivial change — config tweak, copy update, 1-line fix |
| S | 2 | half day | Simple and well-understood — add a field, small bug fix |
| M | 3-5 | 1-2 days | Moderate complexity — new endpoint, simple component |
| L | 8 | 3-5 days | Complex — new feature touching multiple layers |
| XL | 13 | 1-2 weeks | Very complex — new subsystem, major refactor |
| XXL | — | > 2 weeks | Must be broken down further |

Use when auditing a repository's uncommitted or messy changes and restructuring them into clean, logical commits. Enforces zero AI co-author footers and groups related files by domain.
Converts a structured decisions document into .claude/rules/ files (frontend.md, backend.md, security.md, infra.md). Called by the rules-writer agent after architect or rules-lock interview completes.
Systematic codebase analysis — architecture, tech stack, code patterns, brand guidelines, and provider doc health. Produces a structured Codebase Digest consumed by other agents.
Validates and updates provider docs (CLAUDE.md, GEMINI.md, AGENTS.md, WARP.md) for staleness after task execution. Also updates CHANGELOG.md and TASKS.md checklist.
Token-aware session planning. Takes a list of goals/tasks and produces a prioritized TASKS.md checklist split across sessions based on estimated token usage and complexity.
Prompt the user to save the current agent output as a markdown spec file. Handles y/n prompt, target directory selection, filename generation, and file writing. Use at the end of any agent workflow.
